I won't disclose the questions, but there were 5 rounds: 1. An online coding test (less focus on Algorithmics than in other companies, but code quality matters). I had 48h to complete it. 2. HR interview 3. Technical interview (programming languages / systems questions, data structures) 4. Final round (consisted of 3 interviews: one Algorithmics/Maths, one describing in detail a project I've done in the past and one 'Systems interview')
